Dutch auction also known as an open descending price auction. In the traditional Dutch auction the auctioneer begins with a high asking price for some quantity of like items; the price is lowered until a participant is willing to accept the auctioneer's price for some quantity of the goods in the lot or until the seller's reserve price is met. If the first bidder does not purchase the entire lot, the auctioneer continues lowering the price until all of the items have been bid for or the reserve price is reached. Items are allocated based on bid order; the highest bidder selects their item(s) first followed by the second highest bidder, etc. In a modification, all of the winning participants pay only the last announced price for the items that they bid on. The Dutch auction is named for its best known example, the Dutch tulip auctions. ("Dutch auction" is also sometimes used to describe online auctions where several identical goods are sold simultaneously to an equal number of high bidders.) In addition to cut flower sales in the Netherlands, Dutch auctions have also been used for perishable commodities such as fish and tobacco. The Dutch auction is not widely used, except in market orders in stock or currency exchanges, which are functionally identical.
Internet auctions typically last seven days, and operate like eBay auctions. Each listing links to the auction house website where bids can be placed. From that site, bidders are asked to register in order to bid on a vehicle. Live auctions are public auctions held at a specific date and location and are usually published in newspapers in addition to the online listing at GovSales.
To bid, you'll mostly need to go to an auction house on the day and bid in person. However, some auction houses now offer live internet or telephone bidding. You'll have to register to bid with the auction house, whether you're bidding in person or not. You should be able to find out when the next police auction will be held by visiting the auction house's website.
